I'm using PSPICE for TI and attempting to simulate the OAP4140 (transient analysis).
Any time I change the negative supply to a value other than the same value for the positive supply, the simulation fails.
For instance, the standard Reference design from PSICE for TI for the OPA4140, schematic1, Page 1 shows a follower configuration with Vcc = 18V and Vee = -18V. This runs a transient analysis properly. If I change the Vee supply to, say -12V, the simulation fails.
What is causing this and what is the workaround?
